After four centuries a quote from Galileo Galilei is still the most effective way to
introduce a Metrology book: “Measure what is measurable, and make measurable
what is not so”. Every human activity needs an objective measurement and every
global process should be supported by a common standard.
There are several handbooks, tutorials and journals that focus on the basic concepts of
metrology, the uncertainty theory and the international reference standards.
Moreover, the engineering literature is awash with measurement methods for each

The end frequency value must not be less than the start frequency value, and both must be
greater than zero. The whole sweep must include at least one point. If a group delay (G
suffix) is specified as an output, the frequency steps must be close enough together that
the phase of that output changes smoothly from one frequency to the next. Calculate group
delay by subtracting the phases of successive outputs and dividing by the frequency
